„Developments improving the traffic safety on the network of national

public roads”

Zoltán Nagy Magyar Közút NZRT

So many countries, so many problems

It isn’t an accident, it is a snapshot of a traffic situation in India

Rounabout in Atlanta

Road in China in a rocky wall

Passive protection

Snapshot of a Hungarian traffic situation

Snapshot of the current and not momentary state of a Hungarian main road

• Each country has its special problems• It’s very hard to decide the targeted fields

(everything would be important)• It’s very easy to decide the targeted fields (after all

we can’t do anything wrong)• The EU membership helps (in financing,

expectations)– BUT, …. Let’s not misinterprete PROTECTION OF

THE ENVIRONMENT a lot of trees must be cut to produce enough paper to write down the justifications supporting the projects we think requiring explanations + the human resources required for this mean also the wasting of our environmental values.

What to do for increasing the security?

• Discussions of former years• Pavement state – traffic techniques – environment.• The traffic security is not equal to the application

of traffic signs• After 22 years, the complexity for the first time • Where do the accidents happen?• Why do the accidents happen? • The role of the public road infrastructure?• Searching the focus• What do we do?

An example of this dilemma

„Perfect” roundabout, but there are more accidents.Traffic regulation in order.Pavement, draining in order.Fields of vision in order.

Problem:SPEEDSolution: the decrease of speed Philosophic issueTraffipax or rebuilding

The program is made up

Serial no. of type Type of intervention No. of sites

1 Reconstruction, enlargement of roundabouts 11 sites

2 Installation of traffic lights for the traffic management 19 sites

3 Making the pedestrian circulation safer of the bus-inlets at outskirts 54 helyszínen

4 Improvement of pavement

5 sites

5.1 Change by quality improvement of the guardrails of main roads 195,4 km

5.2 Guardrails of main roads, new construction 59,6 km

6Minor intervention in the traffic techniques, installation of public road lighting 33 sites

7 Pedestrian crossings in city area 11 sites

8 Modernization of traffic lights 712 pc

Sites under development

Results of former yearsAt the site of 77 interventions instead of 42 12 mortal accidents, instead of 196, 70 grave

injured, and instead of 204, 113 slight injuries occurred.

Bus stop program

• There is a pedestrian circulation depending on the bus time table, thus from time to time and only on the way to the bus stop

• Is it justified to protect the pedestrians?• Is it justified to limit the speed 24/24 hours

outside the habited areas?• OBJECTIVE: increasing the safety of pedestrians

crossing the driveway, but only when there is a pedestrian passing

Automatic or manual check in for crossing

• Placing of signs with changeable signalization, the image of the signal is changed by button pushing activated by the pedestrians for crossing.

• The pedestrians’ movements must be focused on the access of bus stops.

• Informative boards should be placed for the pedestrians.

• Placing of general removal sings is required after passing the bus stop.

• Te devices to be installed should store the moments of functionning, the operation for adequate time.

Guardrail program

Higher retaining degree at 250 km

Almost one third of accidents is occurring due to way leaving

Program of traffic lights

200 accidents occur annually at roundabouts equipped with traffic lights

• Changing the traditional wire bulbs to LED spots at the roundabouts with lights (improvement of visibility)

• program-supervision (should be intelligent) • Establishment of vehicle sensors to assure the

traffic dependant way of operation (I am just standing, but don’t understand)

• Unified controlling system (quick intervention)

Program of pedestrian crossing

37 injured persons in the last 5 years

• Increasing the traffic security at 11 sites • Middle islets constructed• with relocation of traffic lights• With installation of traffic lights,• Narrowing of roaddrive for speed decreasing, • installation of pedestrian barriers,• installation of durable pavement signs.

The task is complex

• At many sites,• Different type of problems,• Many type of problems, • But the realization is always implemented for the

improvement of the traffic safety.

We do expect

• Safer traffic feeling, improvement of the life quality.

• The minimum objective in figures is:– To have less injured by one hundred

annually !– To save at least 3 lives every year !

But I am confident to realize at least three times better results on the ground of our achievements

Thank you for the attention
